Offsite Add-ons Information

The following is a list of external links to other great and helpful add-ons for Firefox that we recommend. We are in the process of creating guides for them and as they are completed, they will be added to this page so be sure to bookmark us.

OpenDyslexic
Format pages using the OpenDyslexic font and low contrast help. Open-Dyslexic is an open sourced font created to increase readability for readers with dyslexia.

Default FullZoom Level
Provides several options for zooming in and out of web pages including separate ways to quickly zoom text only or full page zoom through toolbar buttons or status bar menu and provides a status bar magnification level display.

Web Slide Show
View images on a web page in full screen slide show format, or a single image in full screen. Options to have images fit the screen (increases visibility of small images), zoom in/out, set minimum image dimensions, and many more customization settings.

Image Zoom
Highly popular customizable image zooming extension accessible via right click. Zoom in up to 400%, fit image feature, auto-centering, and more. Each image can be viewed with different zoom settings instead of just full page zoom. Great for enlarging CAPTCHAS to solve them.

NoSquint
Allows you to customize zoom settings (both text and full page zoom), and foreground and background colors for each site individually. You can also create a global default to cover all sites that you visit.

HYPER-ANCHOR
Hyper Anchor allows you to bookmark the position of highlighted elements on web pages (text, images, etc) and when you click on that bookmark you'll be taken to not only the web page that you bookmarked but the location on the page of the highlighted element. This is very useful for when you visit web pages that are very long.

Wired-Marker
Wired Marker offers a permanent highlighter feature that provides the same functionality of bookmarking web page elements as Hyper Anchor does but it provides many more features and customization options such as automatic saving when capturing an element, customizable highlight colors, folder creation and management of highlighted elements and more.
